About the bike. 1972 Combat Commando. Crankcase oil ways have been sorted. Timing cover and oil pump upgraded by AMR. New main bearings., pistons and rings, cylinder head rebuilt by JimC, JS1 cam and radiused followers. New Amal Premiers with 220 mains, 106 and needle clips on the top grove. I have a K&N short filter because of the electric start. Chokes are present. Floats set to .080" The bike starts easily and pulls strongly. I can't seem to get a steady idle. I did set it up using 3/16" rods to sinc. Throttle seems fine , snaps to return as expected. Was a bit of blue/white smoke on the right side first few times, you can see it in the video. The bike surges in RPM (from 1500 to 3ooo) as I make the slightest adjustment on the idle screws. I am not really working with the mixture screws yet. I have been trying for a bit. I was hoping to run the DGR tomorrow but not running like this, its going to be crazy with 400 riders. Thanks for your help. Brian Wondering if there is anyone in the greater LA area that could have a listen and help?
